Abstract (en)
[origin: DE10312176B3] The load switch has the 2 fixed main contact pairs (3,4) for each current phase and a single movable main contact (16), pivoted into 2 different end positions for briding one or other of the fixed main contact pairs. Each of the latter has a lower fixed main contact (8,12), provided by a number of contact lamella (8.1,12.1) coupled to one of other side of the load switch and a relatively insulated upper fixed main contact (9,13) coupled to a common load switch point and permanently contacted by the movable main contact. Each contact lamella is deflected by a contact spring (10,14) with a longitudinal axis extending in the same direction as the impact direction of the contact surface (19,20) of the movable main contact.
